Looking at your second picture where the wetness is, this is where your tiles over lap.
The underlap (tile under the one above it) has 2-3 grooves in it and they also serve the purpose of water runways between the tile joins.
From the top of your roof, all it takes is a bit of moss to build up in the upper groove and hey presto, leaks.
You have clay tiles and they are prone to growing moss.

On the second picture you have shown, the side to side gap where the tiles overlap, appears wider at the top ?
Some tile realignment might be needed, especially if you have had someone doing work on your roof at some point ?

Yours appear to be glazed tiles (?), but the unglazed clay tiles are like a sponge.
They can be wet, but not drip.

Sometimes these clay tiles can be bowed and if that's on one of these tile runways and bowed in a downward direction, you are more likely going to get leaks on heavy rain periods.

Thanks wotsup, we had the insurance inspector in yesterday, they might get an inspector to have a look at the roof, if they dont i will anyway, it seems none of the houses like mine in area have sarking, insurance inspector was flown up from Melbourne, he said no houses in Melbourne have sarking?, anyway a few of the neighbours had same thing but not as bad, its the first time in 5 years and we have had some ripper storms, lots of folks are way worse off so than us so i wont complain, but if i built a house i would never have a tile roof, and thanks again..
