So what does it mean having estimates on Thursday and Friday?

It means the Senate doesn’t sit for long. Today is a short day (parliament sat at noon) and then there is tomorrow, where the government will push through the supply bills (the legislation that keeps the money flowing) and then there is the environmental amendments, which the government wants to rush through, but given the Greens and the crossbench are against them, puts the Coalition in the box seat.

So that is a very tight two days of senate sittings before estimates begins on Thursday.
