It’s been a while since I went out to Stromlo (the mountain the observatory is on) we took the kids and yes the feedback was.. it’s okay.
You are right about the War memorial, it is something else, currently it’s a massive construction site though.
For me, Canberra is all about the balance it affords, being able to maintain a quasi city convenience lifestyle (and command a competitive salary as a result), good schools, sensible planning etc while still having very easy access to the multiple nature reserves and the ability to easily be alone is the selling point for me.
Below is a picture from the summit of the Mount Tennant trig point within the Rob Roy Reserve to Canberras south (excuse the shoes hehe), access to the reserve is under 10 minutes walk from my house, my kids schools are also about 10 minutes walk from my house.
Local area shopping centre is about a 15-20 minute walk at a casual pace.
Though I try to work from home where possible, being only a 30 minute drive from the city is a blessing.
