Hi Lu and Karen,
I found Blanche Madeline registered in Albury NSW (a long way from Tasmania) in 1878 so she was 22 when she married in NZ in 1900. She is registered as Madeline.
It seems the family was moving between Beechworth in Victoria and somewhere near Albury as this is the registration district.
According to other research which I have checked, where I can, against the Victorian BDMs
Robert McCAMEY b.c 20 Feb 1815 m Mary Jane JACKSON in Tyrone.
Robert was a landholder at Killyneery, Parish of Carnteel, Tyrone
in Griffiths Evaluation. (Between Ballygawley and Aughnacloy)
They had Madeline McCAMEY b.c1845 d.2 April 1882 Sandridge, Victoria, Australia
(Migrated to Victoria, Australia 1864)
m 8 Oct 1868 (Vic.) Giles Escott ROBINSON
It is a bit hard to work out so I hope it makes sense
Robert Henry Giles born Beechworth 1869
Eliza Mary Jane 1871 Beechworth
Giles Escott died Beechworth aged 1 year in 1874 listed as born NSW
NSW (all registered at Albury)
Giles Escott McC born 1873 (has to be the one who died at Beechworth)
Giles R born 1874
Giles E born 1876
Madeline born 1878
Deaths NSW
John 1877
Robert H G 1874
So Madeline the mother died when daughter Madeline was 4.
Giles was born in Reading according to the marriage index married his brother Henry Giles Robinson's widow Julia Ellen Bushell (var spellings) in 1885 in QLD. She had married Henry in 1863 in Victoria (index says Bathgate).
They had a few children at Beechworth. Henry Edward seems to be their last in 1872
Hope this helps to fill in some gaps. 
Meg.
Hello Meg7 : (my first attempt at sending a message - by way of posting a reply, please bear with me)
If this is the way to comment on your post, quoted above, I hope you may be able to assist in matters relating to "Giles Escott ROBINSON".
As it is some time since you , and your correspondents - Lucy2 and karenoz, were interested in this guy I hope you may have time to reconsider details relating to him.
My interest is as a descendant of the individuals you referred to as 'Julia Ellen Bushell' and 'Henry Giles Robinson'.
Hope you may have time to respond.
Many thanks & best wishes for a successful 2012
