Election Express takes us around the country, to the regions and communities, to hear who the candidates are and what's making headlines.

This week, we look at two seats in two very different parts of Australia.

There's an astonishing contest emerging in Perth's affluent, established coastal suburbs where the seat of Curtin has always been a banked victory for the Liberal Party – it was once Julie Bishop's seat and the independent challenger has a deep Liberal Party heritage.

And over on the other side of the country, we're heading to the tip of north Queensland, which is part of the seat of Leichhardt held by long serving MP Warren Entsch. He wanted to throw in the towel, but he's standing again.
