This may be of interest. Medicare bulk billing fees  have been frozen for some time, as have DVA payments for gold and white cards. Some high end specialists have been refusing to see veterans on gold and white cards, purely because DVA are not paying what the DR's say are market rates. Part of the correspondence to and fro contains this snippet of interest to medicare members. This letter was written in 2018, I believe.
" 
In two lengthy paragraphs, Mr Chester explains to Ms Sudmalis that [and I paraphrase] indexation of GP bulk-billing fees under Medicare, which had also been frozen in the past, were unfrozen on 1 July last year, standard GP and specialist fees were unfrozen on 1 July this year and specialist and specialist procedures would be unfrozen on 1 July next year." I  have no idea of the new rates.
