Au-Struck: A Journey Along the East Australian Current

The coast of Port Stephens.

If there were to be a national billfish of Australia, it would certainly have to be the black marlin. But our famed east coast has so much more to offer beyond the Great Barrier Reef heavy tackle fishery that immediately springs to mind when anglers fantasize about traveling to the other side of the globe. World-class numbers of blues, stripes and juvenile black marlin exist, as well as a flourishing broadbill fishery. Realistically, visiting anglers can experience stunning action every month of the year.

Australia is a unique country and island continent, with the east coastline spanning nearly 3,500 miles from Cairns to Melbourne. To put it into perspective, this is about 300 miles greater than the distance from Florida to Maine. It’s a massive amount of coast to explore. The diverse local fisheries range from the warm tropical waters off Cairns and the Great Barrier Reef to the cool and nutrient-rich deeper waters of the Tasman Sea off New South Wales (NSW).

Offshore encounters are influenced by the East Australian Current (EAC), a ribbon of water linking the Coral and Tasman seas. This current pushes against the Australian continent and gathers momentum as it passes through southeast Queensland and into northern NSW.

As these narrow, deep-reaching warmer waters are transported south, they converge with certain geographic features of the coastline and mix with the colder southern water, where large eddies are formed, creating distinct pelagic playgrounds. Ideal conditions appeal to migrating black marlin and might delay their movement south for months at a time. These identifiable features, and the temperature breaks they bring about, also attract blue and striped marlin. One of these eddies forms seasonally off Port Stephens, producing the famous marlin mecca known as the Car Park. In its counterclockwise flow, the EAC also slams the coast of Seal Rocks and then surges east out to sea. Creating a natural eddy, this feature transforms canyons into football fields of bait as the fast-moving current returns back inshore.

Continuing south along NSW into Victoria and down to Tasmania, the continental shelf is at its closest point to shore. The proximity of the shelf, where relatively shallow waters of around 200 meters drop off to thousands of meters deep, makes this part of the coastline very appealing and accessible to trailerboat fishermen. And it is this environment with its deep bathymetric structure that is also home to a burgeoning daytime swordfish fishery. Already, the waters there are producing big fish in surprisingly consistent numbers.

The Big 4

Black Marlin

Mature blacks are remarkable, but juveniles foraging the flats provide unforgettable experiences.

Statistics from the NSW Department of Primary Industries, who have administered Australia’s billfish tagging program since 1973, indicate that black marlin are tagged in Australia in excess of twice as often as any other species of billfish each year. For anglers who want a black marlin on their billfish royal slam bucket list, Australia is a must-visit destination.

Of course, the Cairns giant black marlin fishery, already more than 50 years young, remains the most reliable place in the world to target the heavy tackle fish. From September to December, adult specimens are drawn to the area by both an abundant food supply as well as the warmer waters preferred by the highly fecund females, generally 26-27 degrees Celsius, and the proximity of other breeding age fish. The charter fleet follows this stock up and down a 100-mile stretch of reef. To stay on the main body of fish, liveaboard or mothership charters are recommended.

The opportunity to catch a grander is certainly exciting, but there’s another black marlin fishery that’s equally gripping. We start catching the juveniles, the product of the previous year’s big fish season, as early as March and April. As soon as they are large enough to take a bait or lure, it is game on. Australians refer to these very small 3-4kg fish as micros. In this arena, you can’t look past Fraser Island where 20-plus fish days are feasible. Fraser has two distinct runs of these light tackle micro marlin. The first occurs over the Australian winter, with smaller fish in the sub-kg range, which are the outcome of a more southern spawn beyond Cairns.

Although the juvies are still caught in good numbers through August and September, bites pick up in October and November. Then, a second wave typically passes through. These fish were previously foraging off Cairns and Townsville, following that inshore 30-meter line and bait southward. During this time, it’s possible to catch the little blacks inside of Fraser Island in the waters off Rooney Point. This is a unique place where baby marlin are known to be present in numbers. Without a doubt, it is the best spot in the world to catch a black marlin on fly.

According to Dr. Julian Pepperell, known fondly to Australian game fishermen as Dr. Fish and one of our most prominent billfish scientists, there is zero correlation between a good Cairns marlin season and a resulting positive light tackle season. A single adult female can produce more than 40 million eggs, so it is not the number of larvae they produce is not important. Only when the conditions are ripe for their survival do the fish flourish and our light tackle seasons run hot.

During their early lives, juvenile black marlin are an acrobatic and entertaining fish on light and ultralight tackle. They are
also easy to catch, as they feed voraciously to gain body mass and move up the food chain. Throughout the year these feisty fish eat their way down the east coast, producing a vibrant fishery beyond the traditional North Queensland light tackle grounds.

Australia was made for adventuring, and the Gold Coast has dazzled as a superb fishing destination. For overseas travelers looking to enjoy a summer-style Christmas down under, the Gold Coast is the place to be. Renowned for its white sand beaches with popularized surf breaks such as Snapper Rocks and Burleigh Heads, the area is also Australia’s holiday playground with plenty to entertain, including a number of theme parks and accommodation options to suit any budget. Black marlin generally begin to filter through these waters in December and can be encountered all the way through March. By the time their southern migration reaches the Gold Coast, they are now in the 20kg range and can be caught in double digits.

The fish that start their sportfishing careers as sub-10kg models can reach up to 25 kg by the time they reach Port Stephens, one of the most southern points of reliable black marlin fishing in February and March, which puts them at just over one year of age. While the juveniles often make a return trip north after their southern migration, as is evidenced by tagging recaptures, little is known of their early life beyond that first year.

Striped Marlin

Two areas of Australia’s east coast are most synonymous with striped marlin—Port Stephens and Bermagui. But in fact, they are caught all along the NSW coast in great numbers. And with only a day of travel between these two destinations, with a finger on the pulse you can follow the fish and stay on the bite as it meanders north and south.

Striped marlin emerge in strong numbers each year in the summer months from December through April. Traditionally, the hottest fishing occurs in February and March. Port Stephens is home to Australia’s largest game fishing tournament, the NSW Game Fishing Association’s Interclub, which is held annually the last week of February. This tournament, and the fishing on either side, has produced big numbers of striped marlin as well as heaps of blacks mixed in. Throw in a blue and you’ve got yourself a grand slam! Port is probably one of the best chances for a daily grand slam in Australia and multiple grand slams in a single day are not uncommon when the fishing is firing. If you’re visiting Sydney, then it’s just a hop, skip and jump north by train or car.

An average-sized striped marlin here falls into the 70- 120kg range, which makes for great fishing on stand-up tackle. Striped marlin, like blues, are quite nomadic and hard to pinpoint at times but the NSW fishery has been very reliable for decades due to the massive amount of bait deposited here courtesy of the EAC. Bermagui, or Bermi as we call it, is a quiet town on the Sapphire Coast and the point where the continental shelf drifts closest to the mainland. American author Zane Grey wrote about the legendary waters well-known for their jumbo striped marlin. Still, anglers report a fair share of blues and blacks from January to March. And when the marlin season slows, tuna fishing prospers.

Blue Marlin

Most of the blue marlin fishing in Australia occurs along the continental shelf. Fraser Island, with seemingly more and more catch effort each year, produces the best fishing for blues coming into summer during the months of October and November. The sandy island’s bays and points provide a safe anchorage in various weather conditions allowing for multiple-day expeditions staying out closer to the fishing. Double figure days are very possible during peak activity. With the juvenile blacks still frequenting the area in big numbers during the same period, throw in a big stripe on the edge, which are often caught among the blues, and you have another potential grand slam hotspot.

Further south on the Gold Coast, blues can be caught almost year-round, although the fish seem to run most consistently during April and May when four or five fish days can be commonplace. What’s nice is that the run is quite reasonable with the grounds only 20 miles offshore. These fish often fall in the 100-200kg range. For bigger fish, traditionally the south coast of NSW was considered the main contender for Australia’s first grander blue marlin until the title was unceremoniously stolen by Exmouth, WA in 2018. Conversely, while the fleet instead focuses on big blacks, there has been a good number of blue marlin over 800 lbs. weighed in Cairns.

Daytime swordfishing is a relatively new endeavor in Australia and it has only been in the last decade that recreational exploits have highlighted exceptional fisheries in Tasmania and far eastern Victoria. Richie Abela started Australia’s first dedicated daytime swordfishing charter operation in 2017, Dream Catcher II Sport Fishing, and believes that the region deserves worldwide attention. Regardless of where they are captured, anything over 100kg is considered a big sword, and these waters produce fish of this scale very easily.

Though recovering from devastating brushfires, Mallacoota is the place to go for daytime swordfish on Australia’s mainland. The small holiday and fishing town in the far eastern corner of Victoria provides relatively easy access to miles of rich canyon structures offshore. During the peak months of May and June, the results have been extraordinary, with recent highlights including one five-day period producing three particularly big fish

Getting There

Visiting Australia from North America is quite the haul, but well worth the time invested. Embarking from the east coast, traveling anglers fly to Los Angeles, then on to Brisbane, Australia. It’s about 15 hours, so don’t forget the latest issue of InTheBite. From Brisbane you can stretch your legs near the Gold Coast, which is only 70km south, or head to Victoria and the land of giant broadbills. If the big fish bite is on at the Great Barrier Reef, then it’s best to fly right to Cairns for a night at the Shangri-La Hotel. Early season trips depart from Cairns, but many operations relocate to Cooktown to follow the bite, which is about a three-hour drive north.
