You can use a CC1 filter for daytime colour correction, but mostly the custom white balance will work fine. I have already set a custom white balance in that camera, but you can probably de better.
CC1 filter can be got from here -

Hope this helps!.. A smart Australian like yourself should be able to work it out pretty quick
