Sorry for the late reply. Yes I still have them for sale and Yes I can ship them to you in Australia but that is not included in the plan price, that`s extra.
Also from experience, if you want ALL the plans in a mailing tube, that is fairly Expensive! It is much cheaper if you allow me to fold the plans in a Large Yellow Envelope.
Please PM me with your Full mailing address so I can give you a quote and you can let me know then.
