From what I've been able to work out it seems those who have been extended more than 3 times have been knocked out - although this is only from anecdotal evidence....
Most Melburnians have only been extended twice as we went through one of the last recruitment drives. Our first 6 months started as a lot of others were finishing their first.....
That seems to be the only pattern we can find - again, its subjective and only a few people really know I guess.....
As to whether we'll be employed or not - well we'll know in around 6 weeks or so....
