Scott Morrison has declared Gladys Berejiklian is "no one-trick pony", wishing the NSW premier well despite not joining her at a polling booth on election day.
Both the prime minister and his daughter Lily wore Cronulla Sharks caps when he met with voters at Sylvania Heights Public School, while Lily also wore the local NRL team's jersey.
He was asked why Ms Berejiklian was not with him on Saturday.
"I've spoken to Gladys today I've wished her well and I think she's going to have a great day," he told reporters on Saturday.
"I'm just here at my local electorate where you'd expect me to be."

When Mr Morrison entered the school a Labor volunteer tried his luck at swaying his vote, which he'd already cast.
"There's still a chance for redemption - vote Labor," the volunteer said while trying to hand him a how to vote card.
The prime minister laughed and said "you've got to be kidding mate".
"I believe there will be a good Liberal win today," he told reporters.
"Gladys has shown great discipline and strong leadership, which is how she runs the government, which is why she deserves the support of the people of NSW.
"She's no one-trick pony."
Mr Morrison also grabbed an apron and helped volunteers cook sausages and onions on the barbecue.
Standing next to Miranda MP Eleni Petinos the prime minister warned about a return to Labor - both in NSW and federally.
"The Liberal team here in NSW have transformed the state from the way that Labor trashed it when they were in government for all of those years," he said.
"I don't want to see that come back in NSW, and I certainly don't want to see that come back federally as well."
He said federal Opposition Leader Bill Shorten hadn't been seen often on the NSW campaign trail.
"If he was any further away from NSW this week he would have been in the sea," he said.
