The seat has been held by Liberal MP Peter Abetz since 2008, who won with almost 67 per cent of the votes in the 2013 election.
The next state election is expected to be called for March next year.
When he won in 2013, Mr Abetz had a 16.5 per cent margin, but since redistribution believes it is now about 10 per cent.
Mr Healy was elected to the Gosnells council last year.
He said said he was asked to put his hand up by Labor leader Mark McGowan.
Mr Healy said some of the major issues facing the electorate were funding cuts to Tafe and school
“I am looking forward to having a good conversation about education,” he said.
“The Tafe cuts are grossly unfair. We do a lot of work in careers and some of my Year 12 kids can’t afford to go to Tafe.”
He also said he backed McGowan 100 per cent.
Mr Abetz said it was going to be a tighter election than it was last time.
“I will be running a strong campaign and will be focusing on what I have achieved, including securing funding for the Nicholson Road overpass and a third lane on Ranford Road,” he said.
“Since we have come into government in 2008, we have increased education funding by 69 per cent.”
Labor has been campaigning strongly with its Metronet public transport plan during the past six months.
Mr Healy said he disagreed with Mr Abetz’s comments in Parliament that public transport in the electorate was excellent.
“It’s also crucial that we deliver Metronet to solve the congestion crisis facing Southern River residents every day,” he said.
“Without it, our city will continue to choke.”
Mr Abetz said he had moved the rail extension up on Mr Barnett’s list of projects.
“I have been campaigning on this since 2008 and the then-Labor Government was planning to sell off the land for Canning Vale railway station and I made sure that didn’t proceed,” he said.
