In 2013, Mr Parasiliti, a City of Swan councillor, lost by 24 votes to Mrs Roberts, who has held the safe Labor seat since 1996.
Mrs Roberts said the 2017 State Election was a brilliant result for Labor.
“It is the result of a lot of hard work and it is really gratifying to get such huge support from the community,” she said.

Mrs Roberts said Labor’s focus on jobs was a big factor in the resounding State win for the party.
“A lot of people in the community were very disturbed Tafe fees had gone up so much,” she said.
“Across the board people are concerned education, including trade education, is becoming unaffordable for their kids and grandkids.
“Mark McGowan launched a plan for jobs, while the Liberal Party did not have a proper strategy for job creation in Australia to diversify the economy.”
Mrs Roberts said the proposed sale of Western Power had also hurt the Liberal Party in the contest.
“Once the family jewels are sold, you can’t get them back,” she said.
“You can get a quick sugar hit selling Western Power, but people aren’t just interested in quick fixes and short-term promises.
“The sale of Western Power certainly shifted a lot of votes in the Hills area but the public were also tired of Colin Barnett’s arrogance and the One Nation deal did the party no favours.”
Mrs Roberts said locally she would be rolling out the small grants she had promised in the community, including fencing the school oval in Stratton.
