There are 3 'hills'. 2 on the bike and 1 on the run. The bike one is about 9 or 10 kays out from the start of the lap (I know you are reading dingo and know the actual distance if you want to share). The other side of the same hill is short and sharp. Probably only 500m or so long outbound and 150 or so on the return.
The run leg has a hill, as Toby said, straight out of T2. It would be maybe 200m long and is steepish. It definately has a whole heap of people walking it on lap 2 in the middle to back of the pack. Take note that at the top is a drink station and then a down hill. The down hill is long and gradual and is perfect to recover down. Don't be afraid to run up the hill both times thinking you will leave your heart rate at the top. there are a couple of other gradual inclines and the most annoying is one at one of the turn arounds (up the second side road if you look at the map, maybe 7 kms into the lap) that looks short but hurts a little as you don't really get long enough to recover as it is an undulating part of the course.
The swim is flat, repeat, flat except for the ramp you have to run up out of the water

From memory, you are not allowed to stop between the swim and T1 to take of your wettie either which can suck for those with tight fitting suits.
