Bigbopper,
Royal Brunei are a good airline and you'll be well looked after. It's natural to be concerned about flying but they'll stay on the ground if there's even a slight risk involved. Take a good book, money for food and a spare change of jocks in your carry on luggage in case that happens and you'll be fine. They won't risk you, your fellow pax and a 777 if it looks dodgy. Other posters would be more qualified to comment, but AFAIK Brunei have always had a good maintenance program and well trained pilots (including Aussies, Kiwis and Poms). Australia and New Zealand have excellent safety standards, and a lot of the negative posts you see on here are because everyone working in the aviation industry wants to see that continue, not because there is a serious risk now.
For all the bitching you see on here, there are very few (if any) airlines flying into Australia or New Zealand that would take a serious punt on safety. It's not like Air Afrique are doing business here.
Have a good trip and stay relaxed
