The Red Hot Chili Peppers are using their Big Day Out shows to throw their support behind an anti-whaling campaign.
The rockers are set to headline the Big Day Out festival - including Perth - and will dedicate their performances to the Sea Shepherd Conservation Society.
The Red Hot Chili Peppers will incorporate Sea Shepherd digital visuals into their set and host a stall at each of the venues to provide festival goers with information about the group's campaigns, which include anti-whaling missions and marine conservation.
Sea Shepherd representative Omar Todd wrote on Twitter: "Exciting News! SSCS (Sea Shepherd Conservation Society) are joining the Red Hot Chilli Peppers at Big Day Out 2013! (sic)"
The Red Hot Chili Peppers, who are longtime supporters of the organisation, will play Big Day Out shows in Perth, Sydney, Gold Coast, Adelaide and Melbourne.
Big Day Out kicks off in Sydney on Friday.
