Help identifying fire epaulettes/insignia tabs

[spark driver]

Hi all. I am a volunteer firefighter from Victoria's CFA service and some of my colleagues suggested I go interstate for some advice.

During a recent ebay purchase I became the proud owner of 5 different sets of fire service epaulettes/insignias.

The Lieutenant and Group Officer were easy enough to identify but I am having trouble with the three others (photo attached I hope??).

Any help or guidance with identifying these epaulette/insignia tabs would be appreciated.

The right hand one looks very similar to an Area Manager from UK fire services. Similar to group level officer i guess.
