One trick that an ex used on his job applications( I think he was in the same sector as you) was to copy and paste the job criteria/ key selection criteria etc into the end on his résumé and then change the text color of what he'd copied and pasted to white. That way, it tricks the computer systems that sort applicants into yes and no (based on the words in the application), his application would always end up in the yes file. When his cover letter and resume was printed out or viewed on screen, the 'trick' was invisible because of the white font.
I've used it too and I think it helped my applications get seen more often.
Thanks for the tip, I hadn't heard that idea before. I don't actually have a problem with getting my applications seen or even getting contacted for jobs - I got three contacts yesterday - they may all have been for the same position though. If I was happy to do the full on 40+ hours a week with the added travel to wherever in Melbourne I could have a new job starting on Monday. The whole résumé thing seems not to matter much.

Kids have driven me bonkers with their leaving daycare routine, I leave work at about 4:15 = 4:30 to beat the traffic an get to pick them up by 5:30 and they don't ever want to leave the place, so half an hour is spent faffing around trying to leave. It is good they love the place so much but sometimes I think if it wasn't for the traffic I would be better off just arriving at 5:55 (it shuts at 6:00). DD has begged me so much that she wants to go one Friday (one of her friends only goes on a Friday as is at an ELC kinder the other days) - that I have booked them in for Fri 11th - and I will have a day at home doing a couple of hours work (as a contribution to the extra fees for the day) chilling, and trying to get the house in a fit state for when my parents arrive back.
