Winter 2017


The 2017 pruning season is now well under way at AHA. At this time of year we are always on the look out for either experienced pruners or people keen to learn. If you are interested in joining our team head to the employment section of this website. 

The winter in Margaret River started off with a very dry June and we were all starting to get nervous. However, July has been well above average and now that the soil profiles are at capacity the dams around the region are all starting to fill. 

Other important activities that we complete in winter include weed control, replanting and trellis maintenance. 

Precision Viticulture


The remote sensing of vine vigour has become a popular tool to help grape growers and wine producers identify and manage variation in vine performance across vineyards. Many viticulturists and growers have found airborne imagery to be invaluable for all vineyard operations. Did you forget to order your airborne imagery for this season? If you did, then you will be pleased to know that you may be able to purchase imagery retrospectively through SpecTerra/AHA Viticulture. Please refer to the following website to see if the imagery you are looking for is available.



We provide a monitoring service for many clients in the South West.  A monitoring program provides early detection of vineyard pests, fungal pathogens and bacterial diseases, potentially saving money on sprays or preventing crop damage. Current activities include:

  • Soil pH- should be completed every three years to check the soil's acidity. This data can then be used to make decisions about soil amelioration applications such as lime and gypsum. 
  • Pest and Disease monitoring- with spring approaching our scouts are now checking for early season pests such as snails.

Please contact the office on 97568011 if we can be of assistance in these areas.

Entwine Australia


With vintage now complete we are busy completing audits on all our Quality Assured sites. It is a requirement  to complete an internal audit annually and then every three years we are audited externally by a Freshcare Auditor.   

Entwine Australia is a voluntary enviromental assurance program that allows winemakers and wine grape growers to receive formal certification of their practices according to recognised standards. AHA is currently assisting growers in the region in Freshcare, a WFA approved, independently audited enviromental certification program. Currently we have a number of vineyards accredited so feel free to contact us to see how we can certify you.

Industry Development


Jim Campbell-Clause has been busy collecting soil, water and petiole data from sites in the Geographe to help growers make good irrigation and nutrition decisions. This work has been funded by the Wine Australia Regional Program. Jim is planning a workshop with all participants after harvest and will let you know dates.

Colin Bell continues to be busy with industry development both regionally and nationally. This includes his ongoing represenation on the board of the WGGA.
