Opposition Leader Tony Abbott has encouraged a group of high school netballers to "make body contact" during an election campaign photo call, telling them a little of it never hurt anyone.

Mr Abbott is promising $3 million for a local netball centre of excellence in the western Sydney seat of Reid, and a further $3 million for the 2015 World Netball cup.

While talking to a group of girls Mr Abbott encouraged them to continue demonstrating their "skills" and told them he would "humbly watch" while wishing he was younger again.

And when the young netballers apologised for being sweaty and crushing his suit during the photo call, he told them he did not mind.

Mr Abbott visited the Sydney Olympic Park with his wife Margie and said, as fans of the game, that netball should not miss out on support just because it was not NRL, rugby or soccer.

At the weekend, Mr Abbott's daughters Bridget and Frances said he was a "netball dad" who would barrack for them from their sidelines of their school games so loudly his wife would not stand next to him.

There is speculation Mr Abbott's campaign will take him to Penrith today, where he previously praised local candidate Fiona Scott's "sex appeal".

Reid is currently held by Labor's John Murphy, but government strategists are worried it could be one of several western Sydney seats to fall to the Opposition on election day.
