“Rules for smoothly changing from the old law to the new law”
The law says that there are special rules in Schedule 1AA that explain how changes to this law will work. These rules are called transitional, savings, and related provisions. They help make sure that when the law changes, it doesn’t cause problems for people who were following the old rules. You need to look at Schedule 1AA to see exactly what these special rules say and how they might affect you.
