Hi Paul, if you visit the monastery you are as certain as anything can be in this birding world to see them - which means they will probably have taken a day trip elsewhere!
If they are not at the monastery itself, look on the wires to the east, there is a very rough track about 100 yards back eastwards along the main road leading to a villa - my pair were on the telephone wires along that track.
Went to Monnegre today, which was frankly a bit of a disappointment! It started off well with good views of Black-eared Wheatear at the start of the mountainous section of the road (a reliable spot for them), but as we went along it became obvious that there wasn't much around, probably due to the heat! We had very distant views of Griffons near the "lonesome pine", but none of the area's specialities (Bonelli's Warbler and Eagle, Trumpeter Finch, Rock Sparrow etc) were in evidence. We gave it up as a bad job and continued on to Maigmo where things were a lot better. At the campsite "El Melonero", we saw/heard Crossbill, Crested Tit, Jay, Short-toed Treecreeper, Mistle Thrush, Firecrest and just a glimpse of Rock Bunting, which was a little frustrating as my companion particularly wanted to photograph one.
We went on along the forest track to the top, a viewpoint known as Balcon d'Alacant which gives fine views over the city of Alicante on a clear day, with Coal and Great Tits aplenty. At this location there is a raised concrete base for everyone to stand on and admire the view, and on the city side of the base there were one or two water leaks coming from the concrete which attracted the birds. Imagine our delight when this bird turned up to compensate for the poor views at the campsite!
