The International Gateway is regarded as an ugly eyesore on the butt of Melbourne, still the big yellow pole is hollow and has a stairway leading to the top, so as an Urban Explorer I like it. The Yellow pole has developed a few alternative names. The most common used is Jeff's Dick followed by The Cheese Stick and finally B1's Dick. The inside of the pole has lights however the power is not hooked on, it seems a portable generator is needed. Also tags should be left at the end of the pole, as it shows you have the guts to go all the way to the top.
Jeff Kennett is the premier of Victoria and the one responsible for the creation of the International Gateway. B1 is one of the Bananas from Bananas in Pyjamas.
The picture archive is not complete, I will endeavour to bring you higher quality images of all three sections. Still if you want more go and check these sites yourself and experience it for real.
