One of the problems with the big drive or indeed any first job chasing is that for the number of operators wanting pilots is that there are too many pilots being trained for the number of jobs likely to be available for new first job pilots. Then in the near future we will have a new arrangement that will encourage more Kiwi pilots to come to Australia to compete with local pilots for first jobs.
Sure there are adverts for pilots here in Australia but from my observation most operators are after experienced aircrew. That means more than the basic or minimum number of hours.
For any new pilot and in training the things to think about are getting as many hours as you can log. Also get to fly as many round dial aircraft as you can, The heavier the better. Get some remote experience. A few trips to the Red Centre and landing on dirt strips will help. Nice to have twin and IFR time but most first jobs will be driving a six place single. The twin and IFR experience may be used later. The operator would prefer that you bend the single rather than the more expensive twin. Then if there are vacancies for twin and IFR drivers there are most likely to go to other pilots with the same operator who are the anointed ones to be elevated first to those positions.
Some flight school will have the story of fly with us and you will get a first flying job after you complete training. For someone wanting a GA job that is not always the case, and then there is that big loan to pay back, job or no job.
Keep knocking on doors. Some times it is a case of luck over planning to get that first job.
