Menu Rollover Issue

When you look at the demo page here: http://blueowlcreative.com/wp/savia/contact-us/

then compare that to my site here: http://www.linkaccountants.com.au/contact/

I’m not getting the same nice rollover effect on the top menu.

I’ve installed the theme out of the box and thought that would just work straight away.

What have I not done?
