Why haven;t our petrol and oil prices gotten lower with the recent hike in the Aussie Dollar?

When our Dolalr was worth 65 US cents, we were told that we had to pay more for petrol
and this seemed logical at the time...we all accepted it
...and we had to pay about $1-40 per litre. Bitter pill, but we all understood why it was so damn high.



SO - now that the Aussie Dollar is equal to the US
(ie, gone from US65c to US$1)
shouldn't we be paying around 30% less per litre?


Are we being screwed over or is there a logical explanation?
All answers appreciated thanks.

PS:
We're not hearing much about it in the media - why?
Did someone recently ask for it all to be kept out of the papers?
