To apply for this visa you must have worked for one (1) year in a Specified Regional Area.
See: Specified regional areas
There is no restriction on the type of work that you may undertake. You could work for an employer or yourself. The only restriction is that the employment must be both of the following:
full time
undertaken in a Specified Regional Area in Australia.
The Australian Bureau of Statistics defines a 'full time position' as one in which employment is normally for 35 hours a week. You are allowed to work in up to two (2) concurrent part time jobs to meet the one (1) year (35 hours a week) full time work requirement.
这个说的很清楚。1， 2个限制里面，没有规定2年内所做的工作应该是连续的continous.可以间断
2,第1个限制是full time ，这个底下也解释的很清楚。 需要工作52周以上+所有这52周的工作时间都要超过35hrs（就算你一周内同时为10个雇主工作，你也只能提供2个雇主的工作时间证明来达到35个小时）。不是所有工作时间达到35*52就可以。 （所有低于35小时的周一概不可以计算在内）
可以向雇主索要 reference,自己起草说明移民局的要求，应该没有问题。这个是MUST ，雇主也应该有义务出具这个证明，也不花费他们什么成本。
