Definitely Evie @ Campbell Town:
Firstly, the town itself. It's the only one on the Midland Highway that hasn't been bypassed. As a result, Campbell Town is where *everyone* stops between Hobart and Launceston/Devonport, because here in Tassie, people think 200-300 km is a massive drive and you need a rest halfway
It has everything you'd expect of a highway service centre - multiple food/drink outlets, park, toilets, etc. except it's in a nice little historic town, and the council maintains everything as such.
It's such an ideal location that back in 2015 when the AEVA Tasmanian branch was formed, we campaigned for fast charging, with the centrepiece going to be a single a 50 kW fast charger situated in Campbell Town! (We even had a quick and dirty photo mock-up of how it would look!)
So a few years later, when Evie Networks announced that Campbell Town was one of their three sites at which they were going to install 2x 350 kW units, we were thrilled! Even moreso when we found they were planning to install it in the exact car park that we had proposed a few years earlier!
Not only were significant power upgrades required, but the council had some heritage issues with the proposed pole-mounted transformer, so they had to run everything underground. All up it cost them close to $1m to build the site. Even the funding/incentives they received to assist made only a tiny dent in this. They received benefits from TasNetworks (fast charger support scheme), ARENA (as part of their national 350 kW rollout) and the state Government (Round 1 of their ChargeSmart grants).
It was launched in mid-2020, with lots of AEVA members rocking up to support it -

But it was worth it - they have what is probably the prime location across the state (even including the cities), with the design and pre-approval ready to expand to 6 stalls when ready. Less than a year after opening, Evie stated that Campbell Town was their highest activity site nationally (possibly influenced by us having relaxed Covid travel restrictions within the state, and the lack of supercharger alternatives for Tesla owners - but a great spot nonetheless!)
I've used it several times in many different cars (Ioniq, Aus Leaf 40kWh, Jap Leaf 62 kWh, Model 3 - though not my own Model 3, yet!) and never had an issue. Perhaps the Tritium fairies spend a lot of time at this site keeping it in order!
In addition, although we have over a dozen, soon to be many dozens of fast chargers, this single site would be enough to allow a 350km range EV to access almost anywhere in the state, from Cockle Creek to Smithton. A very useful location!
