As far as I am concerned, the Tourist House has the best quality souvenirs.
Near the Tourist House, are several more Souvenir Shops. The nearest shop has quite a good collection and some different items.
Walking towards the city centre, you will come to Albert Street. If you turn left, there is another souvenir shop, this one specializes in cheaper items.
There are plenty more scattered around the city, I just like these as they are close to each other, so I compare items and prices before buying.
The Tea Centre is 100% Australian owned business that sells 180 different blends of Tea from around the World. I think you will find what your wanting here, check on the internet before you go.
Of course a Tea shop has many Tea pots, quite a collection for the collector to have a look at.
They also sell a good collection of items to do with TEA!
The Tourist House or Walkabout Souvenir shop in Queen street mall, is the only shop I have found that sells AUSTRALIAN ABORIGINAL DOLLS
When you enter the shop, walk towards the back and to the stairs on the right hand side of the shop. Follow these to the top, and you will find the Dolls there.....Boys & Girls.
From memory, they were around $25 for a good size doll. 
This area is where you find all types of authentic Aboriginal artwork. Each display has a photo, name and description of the Aboriginal Artist who did the work. The display is excellent!
Do go for a look, even if you don't wish to buy. I asked if I could take photo's, and I was told yes.
The ground floor of the shop has some more Didgeridoo's and a big range of gifts including t/shirts, opal jewellery, sheepskin rugs, crocodile wallets, soft toys, Ugg Boots, Akubra Hats, large display of Boomerangs, children's gifts and many smaller, cheaper souvenirs.
I thought this was the best souvenir shop in the Mall for QUALITY GIFTS.
OPEN...Mon - Fri 8:30 AM - 9:30 PM
Sat - Sun 9:00 AM - 9:30 PM
What to buy: What I like, is a lot of the souvenirs are MADE IN AUSTRALIA and are QUALITY ITEMS.
This is the hub of shopping in Brisbane - with this extensive mall hosting 6 major shopping centres, as well as an array of other stores in between.
Queens Plaza - stage 1 opened in 2005, and a whole new range of designer and specialty stores have come to Brisbane, such as Tiffany Jewelery, Max Mara, Louis Vuitton relocated from Adelaide street, and the revamped David Jones store is included in this site. 5 floors with 90 specialty stores and a large food court to get lost (or broke) in.
Broadway on the Mall - 2 levels + a food court, specialises in clothing and accessories, many of which are for the young - such as the exclusive Bessie Head - not for the faint hearted or empty pocketed! There is a large Harvey Normal store at the top, and an outlet for the Pancake Manor - a family favourite!
The Myer Centre - 5 floors of shopping + a food court. Over 200 stores are held in here - such as Just Jeans, ABC Shop, Body Shop, Colorado Bags, Australian Geographic, Post Office, jewellery stores and many other clothing, accessory and souvenir outlets. There is also a cinema complex in the top level of the centre. All floors feed into the newly refitted Myer store.
The Wintergarden - another 2 level plus a foodcourt shopping centre, housing some exclusive clothing and accessories stores - Midas shoes, Cue, Mambo, RM Williams, Lisa Ho and many more.
Brisbane Arcade - the beautiful tiled 1923 arcade built by the Mayne family, which had traditionally been the location for many trendy young and well established clothes designers - such as Anthony Lee Dower (brilliant short designer who cater for short girls), bridal shops and exclusive shoe and jewellery stores - Robert White in particular - famed for making Elton John's engagement ring for Renata! My favourite haunt - especially during the January mega sale time - when the designers flog off their leftover clothing and fabrics.
Queen Adelaide Building - originally built as convict barracks, now ingeniously recrafted into a shopping centre, with many specialty shops.
What to buy: Whatever your heart desires.
What to pay: Depends on the budget - a little to a very very lot!
