This is what was the intersection of Ladys Walk, Hilltop Crescent and Hillside Crescent.
This is the continuation of Hilltop Crescent south. Somewhere down there is the entrance to the Lookout Reserve which, of course no longer exists.
This is looking west along what might be Hillside Crescent. As you can see the place is pretty accessible but well-behaved and sensible people don't trespass.
This is looking east from the quarry at the base of the hill. I would not go so far as to say the Lookout Reserve was absolutely at the top of this peak but it was somewhere up there. As you can see from Google Maps there is no Lookout Reserve anymore and also there is a track within the prohibited area.
The original flyer, which I have located yet again, says: 'The Vendor is dedicating to the Public the Look-out Reserve, in the centre of Hillside Estate, 700ft. above sea level, for use as a Recreation Reserve and Look Out. All the Blocks are high and command far reaching views.' As mentioned in the previous post, the 50 'Beautifully Situated and Wooded Blocks' were auctioned on Saturday 13 December 1913.
Victoria has tracked the demise of the estate to the voracious Kerr's (then CSR) Quarry over time - some selected images:
One more thing that needs to be noted: the Camberwell and Hawthorn Advertiser of 28 August 1915 p. 7 mentions that surveyors Muntz and Muntz re-submitted the plan for what was described as 'G. Sweet's Hillside estate' because the earlier plan had not complied with Ferntree Gully council's drainage requirements.
