You don’t need to over-plan your mackerel fishing trip to Australia. This species of fish is caught around the year and it is found in large numbers in the Southern part of the country.

But this type of fish is largely sought after by fishermen as it is predatory. You recognize a mackerel by its narrow head and sharp teeth which are spectacular at catching small species of fish.

This is why you can use various types of fish bait to catch mackerel. This species isn’t endangered and you are able to fish it during any season.

You can also see it in aquariums around the country as it attracts visitors with its sharp teeth.



Swordfish is one of the most delicious types of fish you can eat in restaurants around the world. This fish species isn’t only found in Australia, but it has large numbers in the saltwater around the country.
