G'day folks i picked up a tamron 17-50mm AF f/2.8 xr di ii ld 2nd had cheap as i found it to have fungus and dust, in side the front glass. Now i went to clean it off and when i pulled it out i found it to be inbetween the 2 front glass elements is there a way to separate them as i spent a while trying to and doing a little bit of dmg to the plastic caseing. or can you get a replacment. Cheers

Dust in the front is highly unlikely to have any noticeable effect on images. All lenses, even brand new ones, have dust inside.

Fungus is extremely difficult to eradicate, it's tenacious stuff. Have fun taking it apart if you like, but it would be more sensible to junk it and buy a clean one.

Agree with Euan on this one.
Even after removal, if possible, you'll find that the fungi, at the very least could have attacked any coatings the lens surface may have had.
Cheap lenses tend to be cheap for a reason.
Did you buy it from anywhere "hot and humid"?
