Termination for redundancy and reduction of the last salary

I have been working in a private company since September 2006. Recently they made my position redundant, I am now serving my notice period of three months.

I have accrued leave balance so the company forced me to go on leave in order to reduce no of days of leave, I accepted it to adjust my leave days balance against my notice period.

Further, based on the current climate amid Covid 19, can my employer further force me to accept a reduction in salary in the last month of my notice period?

How will this impact my end of service benefits?
