Legal high flier John Hammond has confirmed he will nominate as a Labor candidate for the federal seat of Perth, recently vacated by Tim Hammond for family reasons.

Speaking on 6PR, Mr Hammond said he was preparing the paperwork for his tilt.

However, it has been reported that ALP state secretary Patrick Gorman has the support of senior Labor Party figures.

The federal Greens have announced their candidate to contest the upcoming by-election.

Caroline Perks, a Perth local, has worked as a public servant on climate change policy and has studied and campaigned on the issue in Australia and overseas.

“We need fair representation in parliament - young women, refugees, and people from all socio-economic backgrounds - it’s meant to be the parliament of the people,” she says on her campaign website.

Perth is held by Labor on a 3.3 per cent margin and Labor is viewed as favourite to hold the seat.
