"People were messaging us asking what's the go with wedding gifts, so Kayla and I had a chat and figured we don't need anything but it would be awesome if we could get everyone on board to contribute with what was going on."
Johnson's NRL club, the Cronulla Sharks, are also raising money in aid of the widespread fires, organising an auction of player memorabilia whilst also getting involved in the clean-up of affected communities within the club's catchment area.
"If you ask anyone that's in the position that we're in, giving back is probably the part of our job that's least spoken about but it's the most rewarding for all of us," Johnson said.
"The fact that we're going to get an opportunity to go down to some communities that love their rugby league and love their Sharks is great.
"We're not expecting to change lives – we can't even fathom what they're going through – but if we can just take their mind off it for a split second then it's definitely worth the trip down."
