Tasmania late April 2019
 

You can check climate averages online but it will probably be variable. Certainly not warm. Colder inland than on the coast. We were at Cradle Mountain in January one year and it was freezing.

Hey Ralph! Long time no see!

I wouldn't hesitate visiting in April - we visited in early April one year - the weather was a mixed bag of rain and beautiful sunny days (although I will admit to freezing our bits off in our cabin in Bronte Park because the only heat source was a wood burning stove and the temps were well below the April average).

The bigger issue was closures over Easter, from Good Friday through Monday - nothing was open, including restaurants and gas stations.

I was in Tasmania in early April 2018 only for 5 nights, three nights, one day in Hobart, three days and two nights on Maria Island, where it was very warm and sunny (I felt hot). I experienced one day of cloudy weather in Hobart, but it was not cold, nor did it rain. I'd been to Tasmania before.
If this is your first time visiting Tasmania, I'd suggest saving it for when you'll have more time, at least 8 days, preferably a little more.
Where else were you considering?

Thanks Mel - I'm still kicking! Trying to organize the trip to accommodate everyone's wishes is like herding cats - have nixed the Tasmania option unfortunately :-(

Thanks Kay and Diamantina!
