[7] To date, manufacture of Tim Tams and other Arnott's products has remained largely within Australia, including bakeries in Sydney, Adelaide, and Brisbane.

[8] At the Huntingwood bakery in Western Sydney, the production line turns out about 3,000 Tim Tams per minute and uses 20 tonnes of the biscuit's cream filling and 27 tons of chocolate coating each work day.

[12][13] In 2004, Arnott's caused a controversy when they released limited edition Tim Tam Tia Maria and Kahlua Mint Slice varieties, flavoured with the popular alcoholic liqueurs.

[14] The Australian Drug Foundation suggested selling the biscuits in supermarkets was "potentially dangerous" by "normalising" the taste of alcohol for children.

[15] An Arnott's spokesperson observed that a customer "would need to consume [their] body weight of biscuits every hour to reach a blood-alcohol content of .05".

[18][19] Point of sale displays featured Zumbo pink in contrast to traditional chocolate brown Tim Tam brand colours.

[23][24] During the Valentine's Day period of 2015, Arnott's launched Choc Raspberry and Coconut Cream flavours, again collaborating with Zumbo.

[26] A limited edition "mocktail" Tim Tam range was launched in February 2016 with piña colada, espresso martini and strawberry champagne variants.

[29] In October 2016 they added a mango variety to the range,[30] and in February 2017 they launched four new flavours—including chocolate mint, salted caramel and vanilla, coconut and lychee, and black forest—in partnership with Gelato Messina.

[34] In the United States, in 2017, an additional flavour, dark chocolate-mint, was produced for the American market;[35] it was exclusively sold there until 2022 when they brought out the tim-tam deluxe range.

[41] In 1994, Arnott's cast a pre-fame Cate Blanchett in a television commercial as a woman who asks for "a packet of Tim Tams that never runs out" from a wish-granting genie.

[51] In late 2015, media reported that Coles was attempting to resist price rises to Tim Tam and other Arnott's products.

[70] In 2021 Trader Joe's in the United States released their own take on the biscuit, branding them "Aussie-style Chocolate Crème Sandwich Cookies".
