Greetings cocodu,
In April walking the Overland Track still requires registration and payment of a fee to walk from end to end.
Part of this process is to book the day you are leaving as it is restricted to 34 only leaving per day. (Plus some private walk clients)
If you check out this site and look at how many vacancies there are on any day you can work out how many intend to start the walk on that day.
For April see
https://bookings.overlandtrack.com.au/otbse/controller/fit_booking_tripdetails.aspCurrently there are not many bookings, but 20 days already have starters (eg 20 booked to start on the 9th). This will change dramatically as we get closer to April, so you may neded to think of booking well before hand.
We went in April this year and there were people on every stage - but not too many. I think the max we had was about 20 at Windamere and down to 3 total in 2 of the huts as a minimum. ie My wife and I, plus one other. We also had one night in a tent away from the huts - though others often preferred to use tents at the hut sites to avoid snorers and get a bit more privacy.
A number of our fellow walkers were visiting from overseas.
There is some flexibility around the bookings and no rules on how far you progress each day. Check the notes on the parks site.
You also get extra folk coming into the middle and others coming up from Lake St Clair to Pine Valley. Those who only do part of the track do not have to book or pay.
Having been there in April during good weather I think it is one of the best times. The orange/red of the fagus was glorious.

http://bushwalk.com/forum/viewtopic.php?f=9&t=758Others have walked through solo, but it is still wilderness so be prepared with the right gear and enough food and fuel. We almost ran out of fuel when someone decided to have a loan of our cooker on the first night. It did not register properly with me at the time, but many folk attempt the track without proper preparation and that becomes a burden on others and a danger to themselves. There are some discussions on this forum re suitable equipment and food.
Oh - and it will be cold...
I will leave it to the locals to talk about places to hire gear.
All the best
