The siblings, who are the sons of rugby league great Rod, decided to grow their mullets, as part of the Black Dog Institute's Mullets for Mental Health campaign.

Within a matter of days, a number of Tyran's teammates at the Gerringong Lions, a host of former players such as Rueben Garrick, Jackson Ford and Jack Murchie and countless more from around Group Seven Rugby League circles had jumped on board to 'Team Ty and Cal'.

"We were both speechless with the response and how much the community came together to join and support the cause," Tyran said.

The Wisharts initially set a goal of $1,000 but behind the overwhelming support, the donations kept flowing.

So much, that by the end of September, their team, consisting of close to 100 members, had raised $106,042.

"It's all definitely exceeded our expectations," Tyran, who's loved the diversity of all mullets grown across the region, said.

"Our goal was set to $1,000, so you can imagine how grateful we and the rest of the team are to crack the 100,000 mark.

"We can't thank everyone who has donated, supported and promoted the cause enough."

The brothers have already been in discussions with the Black Dog Institute about what avenues the money was going towards.

"We've talked to the Black Dog Institute and they've said a lot of the money goes towards research for new strategies to prevent suicide," Tyran, who intends to keep his mullet for a while yet to keep the conversation going, said.

"Also, the money goes towards educating people at a young age about depression.

"We really hope someone can benefit positively from the money our team and other people taking part in the fundraiser have raised."

As stoked as the Wisharts are with this response, they know this is only the start.

"A lot of people from around the community have experienced some hardships over the last few months as a result of suicide, some a lot more than others but it's affected a large portion," Tyran said.

"I guess to us it's important because the initiative took place at a very fragile time.

"We hope it's made a positive impact on the benefits of speaking up and talking about personal problems.

"Both Cal and I, as well as a lot of my close personal friends, are always here for anyone who needs support."

On top of this mullet growing, former Gerringong Breaker and current Lions player Josh Maranesi held an auction last week to raise funds for the Black Dog Institute.

The event raised more than $30,000, with items such as a Tyler Wright surfboard, a Sally Fitzgibbons rash-shirt and surfboard, fully signed NRL jerseys from the Manly-Warringah Sea Eagles (courtesy of Rueben Garrick), Penrith Panthers, Sydney Roosters and New Zealand Warriors, an Australian Kangaroos signed 2019 jersey and a special Gerringong signed Dragons jersey, thanks to Jackson Ford and Tariq and Korbin Sims.
