Mirage gearbox oil change, need help!!

[da5e]

Hey all, greetings from Oz!

I have started a 200,000 km service on my Mirage and decided to start with a complete fluids tranfusion, but i've hit a snag i found the plug on the front of the gearbox for the oil but where's the drain plug located?

What volume (Metric please) of oil do you replace (seemed like only 500ml or so came out)

How do you get the oil back into the box?? garden hose and a funnel?

anyone have any clues for me?
