This Megachile bee appears to be covered in honey. In the last photo, you can see a trail of pollen/honey leading from the nest hole at lower left of picture, to the bee. The bee has been identified as Megachile Hackeriapis canifrons by Bernhard Jacobi, who theorizes that the bee must have been caught in the nest behind the pollen/nectar mix of another Megachile bee and had to move through the mix in order to escape the nest.
This fly is so similar to a 'potter wasp', which appears at the same time of year, that I think there must be some mimicry relationship. Body length about 10mm. Small head with all-encompassing eyes. High domed thorax. Very large calypters. On Leptospermum or Kunzea sp. flowers at the edge of a local national park. This critter parasitises spiders.
There were many Nitidulidae beetles inside the compost bin, on top of the soil. Most of them seemed to have at least one red mite attached to them. Some beetles, like this one, carried a heavy load of mites. The mites were identified by a mite expert, via Ken Walker, as being a species of Mesostigmata.
