My Oleanders have had the same symptoms as in the top pic from time to time.  I've just watered and fed them and they've recovered.  Might be a good idea to mulch them as well.  I just use the small stones that result from sifting soil for growing veg in.  The bottom pic doesn't look like Oleander.  Looks more like Pittosporum.

Excellent thanks!
I'll try that, and yes the last one wasn't an Oleander, I think it is a Pittosporum. 
Im going to try the same mulch treatment with them too.

I hope its a simple as a bit of T&C ... I've been panicking about a fungus infestation :/

This is my first time ever attempting not too kill vegetation.
