Yeah I cant say Ive seen any hackers and Im in Aus as well! I was suspicious of acouple of people but mainly because they were very good at aiming or locking down a map, doesnt mean they are hacking though.
I would suggest noting the names of the people and the server you are on and emailing the server provider/admin. Let them sort it out if they want to keep these people off their servers if they are indeed cheating, which is another thing they can check out.
The skill gap in UT3 is still pretty large, I mean Im not a really good player but I can hold my own but there is still occasions where I can almost lock people out of frags and there have been people doing the same to me.
Some people are just really good on certain maps, there has been acouple of incidents where I was getting killed alot without even being able to see who shot me, I can understand being frustrated over that. No need to accuse people of cheating though unless there is actually proof
