I suggest a unit at the Service centre. Depending which side of the bridge that is located, i also suggest the Home Maker centre in Reserve road, St Leonards, and the Super centre at Moore Park. The latter has easy access for those coming in from the South and the former access, but not totally easy, from the North. Both are sufficiently out of the way to make them "destination chargers" rather than daily routine chargers such as a place like St Ives Village shopping centre. Both have toilet facilities and somewhere to get some food. Both have outdoor parking areas that could have a North facing canopy for solar panels installed.
