If I have to go to Brighton from Balham (which I do, next week), does
anyone know of a site that will tell me how far my Oyster PAYG will
take me?

It will take you to the outer boundary of Zone 6.

One would need to touch out at a station in zone 6 in order to
properly use the system and avoid an unresolved journey charge being
applied to the card.


Presumably I would then buy a return ticket from wherever that is and
use my Oyster for the rest. Advice much appreciated.

You need to ask for a "Boundary Zone 6 to Brighton" return.

'Boundary Zone' tickets are only available for use in combination with
Travelcards, as they are an extension of that Travelcard - one cannot
buy Boundary Zone (BZ) tickets without already holding a Travelcard
(and because of the nature of the touch-in touch-out Oyster PAYG
system, BZ tickets *cannot* be combined with Oyster PAYG).

The only way the OP could take advantage of a BZ ticket and use it
with their Oyster card would be if they already held a season
Travelcard loaded on their Oyster card - if so then functionally it
would no different to combining a paper Travelcard with a BZ ticket.
