The Treasury will be opening its book for the Half Year Economic and Fiscal Update today.
Westpac Acting Chief Economist Michael Gordon says it will show us the state of the Government's finances.
He says it's likely to predict flat growth or even a recession like the Reserve Bank has.
Gordon told Tim Dower it will most likely be grim reading for the Government.
He says they will probably be looking at the prospect of a weaker economy than they expected in the Budget.
