This area has been crying out to me for a multicache for a while. There are 4 stage points not too far from each other to gather information to solve the final coordinates. You will be able to be impressed by the new pavilion at the Athletic track and netball courts, then cross the road to a redeveloped park with signboards devoted to the Aboriginal culture of the area .
At the start, you will find yourself at the plaque devoted to the opening of the Duncan MacKinnon Pavilion and Community Room.
it was opened on the ABth day of October 2015. - make your way west and be careful crossing Murrumbeena Road.
Stage 2 is at the plaque of official opening of the Mallambool Reserve
The reserve was opened on CDth March 20EF.
As you walk around the paths here some totem poles are present close to information boards. The numbers you need can be obtained either on the information boards or pressing the corresponding button on the totems. The information is read aloud on a recording.

Stage 3 - When you get to this Information board and totem - at coordinates - or listen to the commentary which actually reads the board information -
"The Boonerwurrung people - Each clan may have consisted of G people or more "
Stage 4 - When you get to this board - According to the text .. "up to H number of eels..."
and - Hakea seeds are .." up to J millimeters long "
Now you have all the numbers - the cache which is a micro and BYO pen - can be found at -
S 37 TU.X E 145 Y.Z where -
T = 2A + C
U = 2F
X = 3G + F - D
Y = C + E + F
Z = (CD) x 2 + ( A times F ) + 2G + (H times J)
( S coordinates sum to 35 ,E coordinates sum to 32)
Please use stealth and tuck the cache back into it's hiding spot.
FTF goes to CivilMadman.
