Contacting case officer about work opportunity (spouse visa)

Hello,

I am UK citizen married to an Australian. In February 2018 we submitted a complete offshore spouse visa application (including health and police checks). We were assigned a case officer a month later who has only contacted us once to clarify the status of an identity document.

I am a specialist doctor and the hospitals in Australia only recruit at certain times of the year. If I miss the next round I could be unemployed for 6 months or more as I'd like to come to Australia as shortly after my visa is granted to be with my spouse.

Can I inform the case officer about this work situation and what is the best way to do it?
I am worried that we will appear to presumptuous or appear to be rushing the case officer.

Thanks for your help.
