Which petrol? LEXUS RX400h

I recently purchased a 2008 RX400h. Have loved the first couple of days driving and now it's time to fill it up?

I'm confused, however. Inside the fuel cap the label says use E10 or above. The manual says higher than 95. I have also been told that regular unleaded 91, is ok.

What do I need to put in the tank tomorrow?

Thanks.

BTW I'm in Australia. Not sure what grade petrol is available in other countries, and whether they have the same rating system.
