Future Trip

off (to)

I'll go back to Australia to work, and then I'm off to New Zealand.

'Off to' is an informal way to say 'going to' or 'leaving for.' Notice the following:

1. I can't believe you're off to college next fall.
   
2. He's off to summer camp next week.
   

the rest of

I want to see the rest of New Zealand.

If you want to see 'the rest of' something this tells us that you have seen part of it, but you want to see the parts that you haven't already see.  It is like saying 'the part that remains.' We can also use this to talk about food, movies, work, a group of people, etc. Notice the following:

1. I'm going to watch the rest of the movie I started last night.
   
2. Did you eat the rest of the pizza?
   

spend time

I'd spend some time lying on the beach.

When you use your time to do something you 'spend time' doing it.  Notice the following:

1. My neck hurts from spending so much time on the phone.
   
2. He spends a lot of his time outside.
   

head (towards)

After that, I'm going to head towards Canada.

'Head towards' is used to show that you are traveling in the direction of something.  This can be used when telling someone how to get to a place and giving them points of reference to travel towards.  Notice the following:

1. He said he was going to head towards Boston after New York.
   
2. You should head towards the supermarket take a left at the second stoplight.
   

immigrated

One of my best friends immigrated to Canada.

If you 'immigrate' to a non-native you come with the intention of living there for a long time or making it a permanent residence. Notice the following:

1. He immigrated to this country five years ago.
   
2. My grandparents immigrated here from the Czech Republic.
