This one is actually Corunastylis rather than Microtis. Microtis would have a longer leaf extending beyond the flowers whereas Corunastylis has a short leaf apressed to the stem and terminating below the flowers. This plant has quite short lateral sepals and small flowers so I would be inclined to call this Corunastylis nuda.

@MattM yeah, I was 100% guessing on these guys. Looking at my guide after seeing your suggestion, and thinking by the swollen ovaries these are actually past flowering, I was thinking these may be Corunastylis formosa, which is locally common and grows in marshy land. What do you think?

I still think nuda is more likely as the lateral sepals are very short. The lateral sepals are supposed to be up to 4 mm in nuda and up to 9 mm in formosa. Even with a bit of shrink associated with the senescence of the flowers, I can't imagine they would shrink that much.

Plants aren't dark enough for C.formosa which is in the C.turfosa, C.arrecta group. C.nuda is the go, it also likes moist areas and grassy flats
