The requirement is 3 months (there are rules on the how the hours are worked out etc to fit in to 3 months, ie squishing it into 3 weeks doing masses of hours doesn't cut it apparently). If she is half way though she really would be better to try to get the whole lot done if she hasn't done any yet. I am not sure what the current season gives around Adelaide in terms of fruit picking or some such. But I am sure something can be found.
I thought it was classed as 'regional' work not rural. The list linked to below shows SA as being classed as all regional.

I'd hope then that so long as the job falls on the list she would be ok. But looking at the list, I am not sure that her job offer will fall in any of the categories but she can check on that to be sure. Did all her previous regional work meet the requirements? If she is not sure she should check it all out and if it hasn't she can make up the time doing fruit picking or some such hopefully. I can't see anywhere on the list that working in a stables with horses would come under the regional work listing (unless perhaps it was a breeding stables or the horses were for meat but again, she needs to clarify this exactly).
Here is a link to the page with more info, but I've copied it over to the post also
