I have just been to Erindale Library. The JP who is there every Saturday has the use of the community room from 11am until 1pm.
We could have it from about 1:15pm to 3:45pm (the library shuts at 4pm on Saturdays). They don't currently have anyone using the room at this time in July, so we could choose whichever Saturday we like. I am currently available any Saturday.
So, is this OK? and which Saturday would you like - 5th, 12th, 19th or 26th July?
http://www.act.gov.au/browse/topics/sport-and-recreation/barbecue-and-picnic-areas is a brochure on parks in the ACT. I looked for ones with gas BBQs and picnic shelter, and came up with - 18 Gungahlin Town Park, 37 Acton Park, 41 Remembance Park, 46 Commonwealth Park, 55 Weston Park, 56 Yarralumla Bay, 60 Telopea Park, 61 Kingston Foreshores, 67 National Arboretum, 68 Stromlo Forest Park, 82 Tuggeranong Town Centre Park, 86 Faden Pines Park, 2 Uridarra Crossing, 14 Honeysuckle (home of the moon walk), 15 Orroral Valley... If we wanted to, there are BBQs at the other end of Wanniassa - in Wheeler Cres opposite where Athllon Drive and Drakeford Drive meet (the park is between the corner and Wheeler Cres).
