This was posted on the PIONEERS OF THE MORNINGTON PENINSULA Facebook page and as it seemed likely that due to a new algorithm, it was going to be deleted by Facebook, rather than copy it into a word file where nobody would see it, I decided to copy it directly into a journal.

Shane Cleave sent me a message, and as I don't know him from a bar of soap, I wasn't going to answer it. Luckily I did. If you or others want me to be able to help you, write a post, starting with my name and then some information, such as in Shane's message.
Shane's message (edited by me.)
I am Shane Cleave from Flinders. If you don’t mind I would like to find out more about the Cleave family. I think they settled in Red Hill South. My grandfather was Walter Cleave. Thank you for your posts.

This was the only result in a "Walter Cleave" trove search limited to the Mornington Standard, Frankston.
Clearing sale—Shoreham, Alex Scott and Co report having held, on the 26th inst, at Wattle Grove, Shoreham, a most successful sale on account of Mrs Smidt, executrix in the estate of the late John J. Smidt, when they disposed of the whole of the cattle, ponies, household funiture and effects at highly satisfactory prices. The properties were not sold by auction, but were subsequently disposed of privately. "Wattle Grove" of 81 acres was purchased by Mr William Batholomew of Flinders, ten acres (on the Dromana and Flinders roads???????) by Mr W. Walter Cleave Jr of Red Hill, half-acre township allotment at Flinders by Mrs C. Johansen.
(P.2, Mornington Standard, Frankston, 3-7-1915.)

As there were possibly dozens of people named Walter Cleave who were totally unrelated to Shane, rather than barking up the wrong tree and catching a red herring, I did a "CLEAVE, RED HILL" search and discovered an Anzac, born in Traralgon, and his brother, also an Anzac.

Shane, because of interaction with descendants, I have been able to write stories about thousands of pioneers about whom I knew nothing at first except a name in rate records or on a parish map. If W. Walter Cleaves was your grandfather, I don't even have those details. Where exactly were the 10 acres on the Dromana and Flinders road? (Melway co-ordinates.) How were W.W., T.E., and C.H. Cleave related to you?

If you or others are able to answer these questions, I will be able to press on with my research.

A WORD OF WARNING.
There is a fair chance that this post will be labelled scam by Facebook's algorithm and deleted by Facebook so I suggest that readers copy it before this happens and write a comment stating that they do not regard it as scam.

Further message from Shane (edited by me.)
Thank you for your reply. (The above post.) Yes, C.H. Cleave was my grandfather's brother. I have his world war medals and more and I am very respectful of them. A cousin of mine, John Tuck, gave them to me. Thank you again for your help. I know a lot about the Tuck side of the family; my grandma was a Tuck, E.Cleave born 1895. She lived (with?) us and told me a lot about about the Tuck side but not the Cleave side. My father A.W Cleave born 1930 👍

CLEAVE—TUCK.—On th 7th September, at St McCartan's Catholic Church, Mornington, by the Rev. Father O'Hagan, William Walter, eldest son of William Walter and Mary Harper Cleave, of Red Hill, to Ethel, second youngest daughter of Elizabeth and the late Thomas Tuck of Flinders.

RE SHANE'S COMMENT: "My father A.W Cleave born 1930"- no birth record was found. However there was one for the daughter* of Albert Bertram Cleave, he being a brother of Theodore Ernest, Charles Harper and William Walter.
