The Beach Protection Authority requires basic data on the For these reasons, the Authority is of the opinion that behaviour of Queensland's beaches in order to provide well published C.O.P.E. data can be used with confidence founded advice on coastal management to Local Authorities. provided the above inherent limitations are recognised. The C.O.P.E. project aims to collect information on wind, waves and beach behaviour in areas where extensive investigations are not practical and where otherwise little 1.6 Presentation of data or no data exist. The purpose of this report is to present C.O.P.E. data for the eleven year period 1979 to 1990 in a useful statistical form. The project is based on the recruitment of volunteer No attempt has been made to interpret the observed data. observers who are prepared to record a series of basic parameters daily for at least a three year period. If the eleven year period is representative of the long term average meteorological conditions, the statistics presented on wind, wave and beach movements can be regarded as 1.2 Site selection typical. However, this recording period may be considered In selecting a site for a C.0.P.E. station, consideration is too short to be representative in terms of the average given to: occurrence of extreme events such as cyclones and floods and this should be taken into account when consideration i~ (a) the general shoreline configuration and the possibility being given to the influence of such events on trends of long of extrapolation of data to other adjacent beaches; term beach behaviour.

Buddina Beach is located within the City of Caloundra and lies approximately 75 kilometres north of Brisbane on the 1.3 Instrumentation south east Queensland coast. It is a 3 kilometre stretch of The C.O.P.E. observers are supplied with a basic kit of coastiine, south of Point Cartwright.
