Blake is an aspiring amateur astronomer. After recently completing a 4-week astronomy course at the Sydney Observatory, he has decided it is time to upgrade his telescope so he can see more stars and planets in the night sky.

He recalls that, at the end of the course, the lead astronomer had recommended Heavenly Bodies as a good place to get a telescope, and that they offer a 10% discount to students of the course.

The following day Blake goes to Heavenly Bodies to check out their range of telescopes. After browsing for a few minutes he is greeted by Ella who asks whether he needs any assistance. Blake explains that he is looking for a tripod-mounted telescope that he can use at home. Blake also says that it is very important that the telescope allows him to see the rings of Saturn, which are of special interest to him.

Ella explains that the Tele6000 would be the perfect model for him and takes Blake over to the display. She tells him that the Tele6000 is one of the most powerful telescopes ever made for home-enthusiasts, and that it would easily allow him to study the rings of Saturn. Based on Ella's glowing recommendation, Blake buys the Tele6000 for $1,950.00, after the 10% discount.

At the counter, Blake notices that there are microscopes on sale. He has also been keen to check out the microfauna in his fish pond at home, so he chooses the Micro2000 which has been marked down by 50% to only $250.00.

As he is leaving the store, Blake sees a sign that states:

Please choose your items carefully. As these instruments are finely crafted scientific tools, no returns will be permitted and Heavenly Bodies accepts no responsibility for items purchased that do not meet your needs.

ALL SALES ARE FINAL.

After using the Tele6000 for three weeks, Blake is disappointed, as this model is clearly not powerful enough to see Saturn's rings, and he is only able to use it for 20 minutes at a time before the internal lamp heats up so much that it starts to burn his face. The tripod mount has also broken. When he contacts Heavenly Bodies to get a replacement part, they inform him that these tripod mounts are no longer available as the Tele6000 is being discontinued.

He is also having issues with the Micro2000. The lens seems to be permanently fogged up, making it impossible to see any detail. He has contacted the manufacturer and they have advised him that it sounds like the microscope must have got wet sometime after delivery to the shop as they are always delivered to retail outlets in waterproof and airtight boxes. When Blake attempts to return the microscope to Heavenly Bodies his request is denied, and he is referred to the sign in the store that he had previously noticed stating that all sales were final and no returns were permitted.

Advise Blake whether Heavenly Bodies has breached any of the provisions of the Australian Consumer Law, including any relevant consumer guarantees, and if so, what remedies Blake may be entitled to. Ensure that you support your answer with any applicable case law or statute.
