supersleuth – SSMA 2015 Schedule 1, Part 2 Section 4:1 states that Any owner, or any person entitled to vote at a general meeting of an owners corporation, may require a motion to be included in the agenda of the next general meeting of the owners corporation.
It is not only the SC that is permitted to submit Motions. Any lot owner is within their rights to submit a Motion, including a Motion with alternative quotes, as long as they undertake the correct procedure indicated in Section 4. The written notice submitted by the owner must include an explanatory note of up to 300 words.
The obtaining of quotes is not one of the functions that may only be delegated to the SC (see SSMA 2015 [s13]).

Once the OC has selected the quote that they prefer out of the three presented at the EGM, and the OC has approved the quote at the EGM by the relevant voting method, then it is immaterial who proposed the quote.
If you are unhappy with the Motion then there is always an option to vote NO.
I am not sure whether this is the case in NSW but … in QLD if the SC has a particular concern about an owner’s Motion then the SC can recommend that the OC members vote NO to the Motion. The reasons for the SC’s recommendation to vote NO can be presented to the OC members via Extra Material when the EGM notice is sent out to all owners. However, the SC must have decided to include this extra material via a majority resolution at an SC meeting prior to the EGM. The submitting of this extra material recommending a NO vote cannot be done on a personal whim – it must have the majority support of the SC and be properly Minuted.
