In short yes. As part of a Uni project I'm assessing the likely routes of local manufacturing in order to identify contaminants and impurities. I'll post findings and conclusions but they will be some time off yet.
As for safrole in Australia. It is commonly sourced from camphor laurel (Cinnamomum Camphora) as this is a pest xenophyte in parts of NSW and Queensland. It is fairly easy to extract, and is also available as a distillate of camphor oil containing a reasonable amount of this alkene, 3,4-methylenedioxy-allyl benzene.
Rhodium seems down at the moment, but they have an excellent paper in the chem section titled "safrolefaq"
Don't get me wrong, the majority of MDMA definitely comes from Europe / Asia / US, but as records show, there are or have been clandestine labs found in Aus. Perth a month ago, from memory. One thing that is fairly likely, is that more people will consider attempting production in the future.
