It is a common usage term, but there is a "club footed" staysail and it is different from a "boomed" staysail.
A "club foot" staysail has a short section of "boom" that does not reach the forestay nor is it mechanically fastened to any structure/rigging.
That short section is laced on to the staysail from the clew to perhaps 1/3 or so of the distance of the foot of the sail.
It serves as a "short boom" for single
line sheeting, whilst still allowing the foot of the sail to take a nice curved shape.
When the sheet is slacked that short section can become a real "Club" to anybody on the foredeck, as well you can imagine.
It is an ancient device now, and thankfully not used anymore but for some reason the term has refused to go away.
I suppose the term hangs-on much as we commonly hear the term "inner forestay", what, does that mean there's an "outer forestay", well there is, but you only find that on something like a clipper ship.
What many call a "forestay" is in reality a "headstay", like it goes from the mast-Head to the stem-Head, it "stays" the Head of the mast.
Unless you have 2 staysails, (a 3 headsail rig,) there is no "inner forestay",
it's just a forestay that you put a forestaysail on.
For the OP, as you're in Oz I have no idea where you could get the fittings you need.
Perhaps you can invent something that can use a section of small spinnaker
