The WiggleZ Dark Energy Survey is a large-scale structure survey of intermediate-redshift ultraviolet-selected (UV-selected) emission-line galaxies scheduled to cover 1000 deg², spanning a broad redshift range 0.2 < z < 1.0. The main scientific goal of the survey is the measurement of baryon acoustic oscillations (BAO) in the galaxy clustering pattern at a significantly higher redshift than previous studies. The BAO may be applied as a standard cosmological ruler to constrain dark energy models. Based on the first 20 per cent of the data set, we present initial results concerning the small-scale clustering of the WiggleZ targets, together with survey forecasts. The WiggleZ galaxy population possesses a clustering length r₀= 4.40±0.12h^–1 Mpc, which is significantly larger than z = 0 UV-selected samples, with a slope γ = 1.92±0.08. This clustering length is comparable to z = 3 Lyman-break galaxies with similar UV luminosities. The clustering strength of the sample increases with optical luminosity, UV luminosity and reddening rest-frame colour. The full survey, scheduled for completion in 2010, will map an effective volume V_eff~ 1 Gpc3 (evaluated at a scale k = 0.15h/Mpc) and will measure the angular diameter distance and Hubble expansion rates in three redshift bins with accuracies of ~5 per cent. We will determine the value of a constant dark energy equation-of-state parameter, w_cons, with a higher precision than existing supernovae observations using an entirely independent technique. The WiggleZ and supernova measurements lie in highly complementary directions in the plane of w_cons and the matter density Ω_m. The forecast using the full combination of WiggleZ, supernova and cosmic microwave background (CMB) data sets is a marginalized error Δw_cons= 0.07, providing a robust and precise measurement of the properties of dark energy including cross-checking of systematic errors.
