Aldi is known for their branding strategy, 'Like brands. Only cheaper', and for selling what many consider 'copycat' products.

Right a research essay describing how have they avoided liability for trade mark infringement (so far) in Australia? Do you think a passing off action might be more successful?

As part of your answer, you should explain the elements of both passing off and trade mark infringement and compare Aldi's approach (either generally, or you might like to focus on a specific product example) with those legal principles.
