The National Kangaroo Protection Coalition says it has 33 animal welfare groups with thousands of members who will boycott Canberra in response to the culls of 7000 kangaroos at the Majura training site and 550 at the Canberra Nature Park.

The group's spokesman, Pat O'Brien, said his group planned to circulate information about the culls to fuel anger.

He said he hoped the tourism ban would pressure Canberra's tourism industry to lobby the ACT Government to change its policy.

''We've been talking about it the last couple of days and we think it's one of the options we've got and probably the strongest option we've got to get the ACT Government to stop killing these kangaroos,'' Mr O'Brien said.

He said he could not provide a list of the members in the group due to some of their relationships with the ACT Government.

He said he believed the Canberra culls were based on unproven science and were motivated by an ACT Government ''hatred with kangaroos''.

Tourism Minister Andrew Barr said the boycott was misguided.

''While I respect the right of those concerned with animal welfare to voice their concerns, it is not fair for them to jeopardise the livelihoods of our hard-working and environmentally sustainable ACT tourism operators and the thousands of Canberrans they employ,'' Mr Barr said.
