Australia State Has Some Questions

I recently bought some Australia State badges in a large set. This is a completely new topic for me. I chose a few pieces and asked for the opinion of professionals.
1. Queensland 1 penny - what is this cancel?
2. SA 1 penny - does this overprint look strange?
3. Tasmania 2 pence - what color is it? the number
4. Tasmania Reveniue pair - if I understood correctly, these stamps have been used since 30 Nov 1900 and the stamps have the date 29 Nov 1900.
5. Tasmania with perforation T - is it real?
6. NSW 3 pence - what color? What number ?
7. SA one shilling - is there anything interesting here?

thank you for all the comments and suggestions

1. A Brisbane type is all I know.
2. Looks like overinking; nothing special as the overprinting is usually somewhat rough.
3. By what catalog? Looks like SG slate green to me. ASCC may be different.
4. Scott 1840-1940 says November 15.
6. Both look like yellow green to me, so Scott 17d. The left one has strongly blued paper, the right one is grayish.
7. Both rightmost stamps are rouletted. Scond stamp top row and second and thrid stamps bottom row show plate wear.

Yes, It is real, it exists.
It is an Official puncture "T" for Tasmania.
Line punctured, hence all sorts of types of "T" exist, in all sorts of varieties.




I don't recall ever seeing this before ..."X"
Look forward to seeing a definite ID...



Looks normal.

Thank you for your help. So only cancel from point 1 is still a mystery?

Sopotsopot, the cancel on your Queensland sideface stamp is a "Pillar Box" type. The upper left and right letters are P and B.

At top centre, the code X is for intercolonial mail (i.e. interstate after federation) with a code number 1 below.

The line below that is BRISBANE - the pillar boxes were located at the Brisbane GPO.

Finally, September 6th, 1898. These cancels have been recorded used from 1886-1910.

This information (and plenty more on the postal history of Brisbane GPO) can be found in Marius Wytenburg's online exhibit.

The first laureate is stamp 7 of row 4. It is cancelled with a Sydney dumb obliterator. The right side of the stamp is absent. I'd say it's SG 65.

The second laureate is stamp 1 of row 3. It's also cancelled with a Sydney dumb obiterator. I'd say this one is SG 87.

Hope this helps

Thank you very much FDS.
Nice work too Bobby.

The Stanley Gibbons Australia catalogue lists the overprinted stamps as issued on 15th November, 1900. The notes below the listing explain that they weren't intended for postal purposes but an ambiguity in regulations permitted their usage until all postal fiscal stamps were invalidated for postal purposes on 30th November 1900.
