Well if the 150 people were sane and wanted to live in Sydney you would assume that all of them would preference WSU higherOn this note I like to explain a little more for general info.
Let's say UNSW has 150 non-rural places to offer. It doesn't necessarily mean you must rank 1st to 150th to get an offer. It could happen 30 of the UNSW's top 150 have pref'ed WSU higher (for its 5yr course) and they also qualify for WSU. UAC deliberately will not give them both offers, instead UAC only offers them WSU and allocates "their" 30 UNSW places to UNSW's 151st to 180th.
Place yourself in the position of those 151st to 180th, would you rather UAC does that so you get a UNSW offer, or UAC offers both to these dual-qualifiers and leaves you hanging?
