I will discuss new constraints on inhomogeneous
Lemaitre-Tolman-Bondi models as an alternative to Dark Energy, arising
mainly from the inclusion of the higher redshift Baryon Acoustic
Oscillation data from the WiggleZ collaboration. Assuming homogeneous big
bang time and baryon fraction, the early time, quasi homogeneous limit of
the model allows the computation of the BAO observables at different
redshifts. LTB models with a CGBH profile are investigated using different
cosmological data, finding that the amount of matter at the center of the
void preferred by Supernovae and BAO is found to be discrepant
at the 3-sigma level. This model is found to be highly disfavoured with
respect to LambdaCDM cosmologies in a Bayesian analysis.
