  The detection of five new fast radio bursts (FRBs) found in the High Time
Resolution Universe high latitude survey is presented. The rate implied is
6$^{+4}_{-3}\times~10^3$ (95%) FRBs sky$^{-1}$ day$^{-1}$ above a fluence of
between 0.13 and 5.9 Jy ms for FRBs between 0.128 and 262 ms in duration. One
of these FRBs has a clear two-component profile, each component is similar to
the known population of single component FRBs and are separated by 2.4(4) ms.
All the FRB components appear to be unresolved following deconvolution with a
scattering tail and accounting for intra-channel smearing. The two-component
FRB also has the highest dispersion measure (1629 pc cm$^{-3}$) of any FRB
to-date. Many of the proposed models to explain FRBs use a single high energy
event involving compact objects (such as neutron star mergers) and therefore
cannot easily explain a two-component FRB. Models that are based on extreme
versions of flaring, pulsing or orbital events however could produce multiple
component profiles. The compatibility of these models and the FRB rate implied
by these detections is discussed.
