A weed is simply any plant that grows where you don't want it. If you plant
Silene maritima (= Silene uniflora)(a.k.a. Sea Campion (note spelling)) in a
spot where it has room to run and keep it under control, it would not be a
weed.

The species is widespread and variable in the Old World flora and has been
divided into a number of subspecies, some of which have a much less weedy
tendency than others. The ssp. found in mountainous regions are probably
less weedy than the coastal ones.

The variegated cultivar Silene uniflora 'Druett's Variegated' is especially
slower growing.

I have found out the name of a plant (thanks to you guys) that I want
to put in my garden, however, it seems that it might be classified as
a weed in some parts of the world. How do I go about finding out
information about these sort of classifications. I am in Adelaide
Australia.
Yes, the plant was Silene Maritima Otheriwse known as Sea Camion, or
CATCH FLY.

P.S. Thank you for the previous replies.
