Outdoor furniture needs a new lease of life

Can someone please tell me what type of wood my new (old) furniture is?
The bench shows some exposed wood which is quite light.
It was fairly dirty so I used the environmentally friendly (and cheap) water blaster on it.

I want to rejuvenate it a bit. So what do you recommend?
From what I understand its been oiled in the past.
Suggestions on what brand is good and for what reason.
I'm trying to keep it reasonably cost effective

Anyway you want to see wood. Here is the WOOD.

Had a setting just like that in fact still have two small tables (folding),wood is Kwila when new is a reddish colou, a bit like Jarrah .Any of the Wattyl brand oils should give you good coverage .Sanding back to bare wood would seem only way of preserving colour etc since it has been vranished
