I'm sorry an answer has taken so long.
I've been an insurance salesman (one of 15 professions lol) , along with a workcover investigator and other tasks associated with compensation.
I have also had a couple of claims that went as long as 10 months post injury.
One thing is certain, the workers compensation system in most or all states is a labyrinth or maze of issues and processes that is deplorable for the injured party. But at the end of the day you have no other option but to accept that it is the way it is. You wont change a system that countless others have complained about.
My first concern for you is to ask if you have a compensation lawyer representing you. This is most important to safeguard your rights which can and often is mildly violated during the said process. If not then seek one out.
Secondly you might be of the opinion that your own GP is all that is needed in terms of his/her support with remaining off work- not so. The insurance company that you are under can send you to one of their approved specialists which frustratingly is pro the insurance companys interest (so they get a good flow of work).
No one case of compensation is comparable to any other. However I'll mention that in my case of 10 months off work (1987) I had to slowly accept that the psychological injury sustained on me meant I could never return to that profession. That meant I had two options- to fight it in a court and hopefully seek a dollar figure of compensation for damages or seek another profession and move on. I chose the latter and in my case I would do the same again today if fronted with such a situation. In the 10 months I was off work I saw my wife and family members suffer around me, my own anger peak and my well being erode.
Once in a different profession it took about 3 months to psychologically recover and feel good. I ended up chucking all the paperwork of my claim in the bin. But thats my case not yours. Yours is for you to decide.
I wish you well. The WC system is full of fraudulent claims hence most cases are investigated to confirm its legitimate. That's the way the game is.
